The DNA of nearly all life on Earth contains many redundancies, and scientists have long wondered whether these redundancies served a purpose or if they were just leftovers from evolutionary processes ...

Somewhere in a sample of ordinary pond water, a single-celled organism has been quietly breaking one of biology’s most ...

To overcome the inherent challenge of translation termination interference caused by stop codon reprogramming in mammalian cells, researchers from Peking University led by Chen Peng from College of ...

A routine experiment with a new single-cell DNA sequencing method turned into a surprising scientific twist when researchers ...

Rule-breaking discovery: A freshwater ciliate uses stop codons to build amino acids instead of ending proteins, defying the 'universal' genetic code. Genetic code flexibility: The organism reassigns ...

Scientists testing a new method of sequencing single cells have unexpectedly changed our understanding of the rules of genetics. The genome of a protist has revealed a seemingly unique divergence in ...

Living organisms synthesize a staggering variety of proteins by combining 20 amino acids into chains of any length and order. In the past, to expand protein diversity beyond the scope of these 20 ...

Genetic activity underlies biological functions, so organisms have to make sure that the right genes are expressed at the ...

Scientists from the Earlham Institute accidentally discovered a single-celled microorganism that violates one of the ...
